                                   THE COMPANY

         We specialize in the architecture, design and delivery of wireless
technology and product platforms. Our current technology development programs
are focused on creating intellectual property and hardware and software products
for the WCDMA specifications of the 3G standard. WCDMA is comprised of two
wideband technologies: FDD and TDD. (Please refer to the Glossary of Terms,
beginning on page 14, for a list and detailed description of the various
technical, industry and other defined terms that are used in this Prospectus.)
Over the course of our corporate history, we have amassed a substantial and
significant library of digital wireless systems experience and know-how and we
hold an extensive worldwide portfolio of patents in the wireless systems field.

         We market our technologies and solutions capabilities primarily to
telecommunications equipment producers and related suppliers. Our inventions are
embedded into products targeted for the following wireless telecommunications
applications: mobile phones, personal digital assistants, mobile computing
devices, other terminal-end wireless devices, base stations and other
infrastructure equipment. In addition, we license our patents to equipment
manufacturers worldwide. We are continuing to broaden and deepen our extensive
patent portfolio and body of technical know-how related to wireless technologies
and systems through continuous invention and innovation, while also linking our
licensing activities to emerging product development efforts, particularly in
those areas related to WCDMA standards.

         We develop advanced wireless technologies and products that facilitate
voice and data communications. We are currently developing WCDMA FDD and WCDMA
TDD technology platforms. Our strategic objective is to create substantial
long-term value as one of the leading developers and providers of advanced
air-interface and full SOC technology for the wireless communications industry.
We expect to create a return on our investment in 3G technologies through
technology transfer to customers, the delivery (either alone or through
alliances) of software and hardware products and the licensing of our
intellectual property worldwide. The development of advanced wireless
technologies focused on market requirements is a fundamental element of our
future strategic success and is key to achieving these goals.

         For the past ten years, we have been intensively involved in a
comprehensive patent licensing program with the ultimate objective of realizing
licensing revenues from use by third parties of inventions covered by ITC's
patent portfolio. ITC offers non-exclusive, royalty bearing patent licenses to
telecommunications manufacturers that manufacture, use or sell, or intend to
manufacture, use or sell, equipment that utilizes our extensive portfolio of
intellectual property. ITC has entered into 30 license agreements with 26
manufacturers, covering the manufacture, sale and use of products complying with
2G and/or 3G standards. Our license agreements are made on a paid-up, prepaid,
or current royalty bearing basis, or a combination thereof. Prepayments are
generally made as advances against payment of future royalties. As sales of
covered products are made, the royalties due are calculated and either applied
against any prepayment, or paid in cash. Sometimes, the royalties due are
applied in full against the prepayment while other times they are applied in
partial satisfaction (e.g., 40%). In the latter case, a royalty would be due for
the remaining amount not applied against the prepayment (e.g., 60%). Royalties
on sales of covered products under the license agreement are payable or
exhausted against prepayments based on the royalty formula applicable to the
particular license agreement. These formulas include flat dollar rates per unit,
percentage of sales, percentage of sales with caps, and other similar measures.
The formulas can also vary by other factors including territory, covered
standards, quantity, and dates sold.

                                      -3-


         In earlier years, the Company developed intellectual property relating
to 2G technologies. As a result, earlier licensing agreements cover the 2G
patents generated from such technology development. ITC continues to seek to
license its 2G patents as such patents have not expired and 2G products are
predominant in today's market. However, the Company also has a significant
number of patents related to 3G technologies, and its continuing to develop 3G
technology, leading to the filing of additional 3G patent applications.
Therefore, ITC's licensing efforts have expanded to cover its 3G patent rights.

                                  RISK FACTORS

         This section highlights specific risks with respect to an investment in
our Company. In analyzing this offering, prospective purchasers should carefully
consider these risks. We caution you that this Prospectus, as well as the
documents that we have filed with the Commission that are incorporated by
reference in this Prospectus, contain forward-looking statements that are based
on management's beliefs and assumptions and on information that is currently
available to us. You should carefully consider the risks and uncertainties
described below and in the documents filed with the Commission that are
incorporated herein by reference before purchasing the Common Stock.

         Forward-looking statements relied upon by management reflect, among
other things, our current intentions and plans or expectations (i) to broaden
our patent portfolio and body of technical know-how, (ii) to link our licensing
activities to emerging product development efforts, (iii) to deliver (either
alone or through alliances) software and hardware products, and (iv) to engage
in technology transfers and license our intellectual property worldwide. Words
such as "objective", "intend", and "expect", variations of such words, and words
with similar meaning or connotations are intended to identify such
forward-looking statements.

         Such statements are subject to risks and uncertainties. We caution
readers that important factors in some cases have affected and, in the future,
could materially affect actual results and cause actual results to differ
materially from the results expressed in any such forward looking statement. You
should not place undue reliance on these forward-looking statements, which apply
on or as of the date of this report. Certain of these risks and uncertainties
are described in greater detail in the Company's Form 10-K for the year ended
December 31, 2001 and Form 10-Q for the quarter ended September 30, 2002. It
should also be noted that risks described as affecting one forward-looking
statement may affect other forward-looking statements. In addition, other
factors may exist that are not fully known to us at this time. We undertake no
obligation to publicly update any forward-looking statements, whether as a
result of new information, future events or otherwise.

Our Use of Arthur Andersen LLP as Our Independent Auditor May Pose Risks
To Us and Limit Your Ability to Seek Potential Recoveries From Them Related to
Their Work

         Section 11(a) of the Securities Act provides that if any part of a
registration statement at the time it becomes effective contains an untrue
statement of a material fact or an omission to state a material fact required to
be stated therein or necessary to make the statements therein not misleading,
any person acquiring a security interest pursuant to such registration statement
(unless it is proved to be that at the time of such acquisition such person knew
of such untruth or omission) may sue, among others, every accountant who has
consented to be named as having prepared or certified any part of the
registration statement or as having prepared or certified any report or
valuation which is used in connection with the registration statement with
respect to the statement in such registration statement, report or valuation
which purports to have been prepared or certified by the accountant. On April
16, 2002, we announced that we had made a determination to engage
PricewaterhouseCoopers LLP ("PwC") to serve as the Company's independent public
accountants and no longer engage Arthur Andersen LLP ("Arthur Andersen") in such
capacity. Our consolidated balance sheets as of December 31, 2001 and 2000, and
the related consolidated statements of operations, stockholders' equity and cash
flows for each of the three years ended December 31, 2001, have been audited by
Arthur Andersen, as stated in their report dated February 14, 2002, included in
our Form 10-K for the year ended December 31, 2001, which is incorporated by
reference in the Registration Statement. Prior to the date of this Prospectus,
the Arthur Andersen engagement partner and engagement manager who reviewed our
most recent audited financial statements resigned from Arthur Andersen. As a
result, after reasonable efforts, we have been unable to obtain Arthur
Andersen's written consent to the incorporation by reference into the
Registration Statement of its audit reports with respect to our financial
statements. Under these circumstances, Rule 437a under the Securities Act
permits us to file the Registration Statement without a written consent from
Arthur Andersen. Accordingly, Arthur Andersen will not be liable to you under
Section 11(a) of the Securities Act because it has not consented to being named
as an expert in the registration statement. In addition, the ability of Arthur
Andersen to satisfy any claims (including claims arising from Arthur Andersen's
provision of auditing and other services to us) may be limited as a practical
matter due to recent events regarding Arthur Andersen.

Our Technologies May Not Be Widely Deployed

         Our activities are focused on next-generation technologies and products
and therefore begin as research and development work. Accordingly, we are
subject to the risks typically associated with such activities. New
technological innovations generally require a substantial investment before they
are commercially viable, and we may make substantial, non-recoverable
investments in new technologies that may not result in meaningful revenues. For
example, in order to generate revenues and profits from sales of 3G Products, we
must continue to make substantial investments and technological innovations. A
significant assumption in our strategic plan is that WCDMA will be widely
deployed in the 3G market (i.e., the market for advanced mobile wireless
products and services). WCDMA may not be deployed as widely as we expect which
could reduce revenue opportunities. A second significant assumption in our
strategic plan is that TDD will be adopted and widely used in the 3G market.
While our inventions and know-how can apply across a broad range of
technologies, our detailed technology and development efforts are primarily
focused on WTDD and FDD. Other digital wireless technologies, particularly
CDMA2000, FDD multi-carrier CDMA technology, W-LAN, FDD used in data
applications, FDD high speed downlink packet access, and NTDD are expected to be
competitive with WTDD. CDMA2000 has been deployed in parts of Asia and the
United States, and such deployment could cause CDMA2000 to gain significant


                                      -5-


market share and reduce the opportunities for WCDMA. W-LAN, which enables users
to connect laptops and personal digital assistants to the Internet, is already
being marketed worldwide and is competitive with TDD. If the initial deployment
of FDD for data applications obtains significant market share, or if FDD high
speed downlink packet access gains market acceptance, the niche targeted for
WTDD could be reduced or eliminated. All of these competing technologies also
could impair multi-vendor and operator support for WTDD, key factors in defining
opportunities in the wireless market. There can be no assurance that our
technology will ultimately have market relevance or be selected by wireless
service providers for their networks or equipment manufacturers. If we determine
that WTDD will not be adopted at all or in a time period we expect, or adopted
in a manner which justifies our continuing investment in the technology, we may
change our strategic plan to reduce or eliminate such continuing investment
and/or to capture more lucrative market opportunities. Additionally, if WTDD is
not adopted and widely used, our strategic plan will require a significant shift
and a portion of our anticipated revenue may not materialize.

Our Future Operating Results are Likely to Fluctuate

         Our financial condition and operating results have fluctuated
significantly in the past and may fluctuate significantly in the future. These
operating results may continue to fluctuate because (i) our markets are subject
to increased competition from other products and technologies and announcements
of new products and technologies by our competitors; (ii) it is difficult to
predict the timing and amount of licensing revenue associated with past
infringement and new licenses, or the timing, nature or amount of revenues
associated with strategic partnerships; (iii) we may not be able to enter into
additional or expanded strategic partnerships or license agreements, either at
all or on acceptable terms; (iv) the strength of our patent portfolio could be
weakened through patents being declared invalid, our claims being narrowed,
design-arounds, changes to the standards, and adverse court decisions; and (v)
our revenues are in large part dependent on sales by our licensees which is
outside of our control. General economic and other conditions causing a downturn
in the market for our products in development or technology could also adversely
affect our operating results. Nevertheless, we base our decisions regarding our
operating expenses and capital expenditures on a combination of current cash
balances, anticipated cash flow trends and the level of expenditures required to
execute our strategic plan. Because the base level of many of our expenses is
relatively fixed, variations in revenue from a small number of customers could
cause our operating results to vary from quarter to quarter and result in
operating income or losses. In addition, increased expenses which could result
from factors such as increased litigation costs or actions designed to keep pace
with technology and product market targets could adversely impact near-term
operating results. The foregoing factors are difficult to forecast and these, as
well as other factors, could adversely affect our quarterly or annual operating
results.

                                      -6-


We Have Substantial Global Competition

         Competition in the wireless telecommunications industry is intense.
There can be no assurance that we will be able to successfully compete in our
efforts to license our technology and/or sell our future products, or that our
competitors will not develop new technologies and products that are more
commercially effective than our own. Our products and services face competition
from existing companies providing services comparable to ours and companies
developing and marketing other digital and wireless technologies. We face
competition from the in-house development teams at semiconductor corporations
and telecommunication equipment suppliers. It is also possible that new
competitors may enter the market. Many current and potential competitors may
have advantages over us, including (a) existing royalty-free cross-licenses to
competing and emerging technologies; (b) longer operating histories and presence
in key markets; (c) greater name recognition; (d) access to larger customer
bases; and (e) greater financial, sales and marketing, manufacturing,
distribution channels, technical and other resources. As a result of these
factors, these competitors may be more successful than us. In addition, the
slowdown in the global economy and anticipated rollout of 3G has forced, and may
continue to force, realignment within the semiconductor industry. Such vertical
and horizontal consolidation could result in increased competition for
partnership opportunities.

We Need to Effect Further Technology and Product Development in a Timely Manner

         Our future success will depend on our ability to continue to develop,
introduce and sell new products, technology and enhancements on a timely basis.
Our future success will also depend on our ability to keep pace with
technological developments, satisfy varying customer requirements, price our
products competitively and achieve market acceptance. The introduction of
products embodying new technologies and the emergence of new industry standards
could render our products and technology currently under development obsolete
and unmarketable. If we fail to anticipate or respond adequately to
technological developments or customer requirements, or experience any
significant delays in development, introduction or shipment of our products and
technology in commercial quantities, our competitive position could be damaged.

         Our positioning for the 3G market will require continued significant
investment in research and development. We cannot be sure that we will have
sufficient resources to make such investments, that we will be able to make the
technological advances necessary to achieve these goals, or that the costs
associated with such efforts will be acceptable. Our business, financial
condition and operating results could be materially adversely affected if we are
unable to respond to the need for technological change or if these products or
technologies do not achieve market acceptance when released.



                                      -7-


         We may experience technical, financial or other difficulties or delays
related to the further development of our technologies. Delays can be costly,
and if such development efforts are not successful or delays are serious, our
existing and potential strategic relationships could suffer or these strategic
partners could be hampered in marketing efforts of products containing our
technologies. We could experience reduced royalty revenues on such
organizations' products containing our technology and/or we could miss a
critical market window. Further, failure to meet material obligations under our
existing or potential contracts could result in the other party terminating the
relationship and/or seeking to hold us liable for breach. Moreover, our
technologies are in the development stage, and have not been fully tested in
commercial use. It is possible that they may not perform as expected or may not
be market relevant. In such case, our business, financial condition and
operating results could be adversely affected.

Our Markets are Unpredictable and Subject to Rapid Technological Change

         2G products and services were introduced in the early 1990s, taking
advantage of new digital technology that greatly increased the capacity, quality
of service and flexibility of wireless networks. In 2001, 2.5G systems (such as
GPRS) began to be deployed offering substantially higher data rate services.
Deployment of 3G services is in its early stages, and is expected to allow
operators to take advantage of additional spectrum and, through the use of
higher data speeds, deliver richer voice and data applications to their
customers.

         We are positioning our current development projects for the emerging 3G
market. These projects do not have direct bearing on the 2.5G or any other
market which might develop after the 2G market but prior to the development of
the 3G market. The 3G market has and may continue to develop at a slower rate or
pace than we have and do expect and may be of a smaller size than we expect. For
example, the potential exists for 3G preemption by the hangover of 2.5G
solutions now being bought, tested and fielded. In addition, there could be
fewer applications for our technology and products than we expect. Economic
conditions, customer buying patterns, timeliness of equipment development,
pricing of 3G infrastructure and mobile products, continued growth in
telecommunications services that would be delivered on 3G devices, and
availability of capital for and the high cost of infrastructure improvements
could also affect the rate and pace of 3G market development. Failure of the 3G
market to materialize to the extent or at the rate which we expect would reduce
our opportunities for sales and licensing and could materially adversely affect
our business, financial condition and operating results.

         The entire wireless communications market in which we compete is
characterized by rapid technological change, frequent product introductions and
evolving industry standards. Existing technology and products become obsolete
and unmarketable when products using new technologies are introduced and new
industry standards emerge. As a result, marketability and the potential life
cycles of the products and technologies that we are developing cannot be assured
and are difficult to estimate. In addition, new industry standards, falling
prices or technology changes may render the products and/or technologies
obsolete or non-competitive. New technologies and products can fail to become
commercially viable due to lack of market relevance. To be successful, we must
continue to develop new products and technologies that successfully respond to
such changes. We may not be able to successfully predict the market or form
strategic relationships, either at all or on acceptable terms, to enable us to
develop such new products and technologies. Even if we do, we may not be able to
introduce such products or technologies successfully in a timely manner. Missing
a critical market window could reduce or eliminate our ability to capitalize on

We Have Arrangements with Third Parties Which Could Expire, Adversely Affecting
Our Cash Flow And Our Ability to Achieve or Sustain Acceptable Levels of
Profitability

         Revenues attributable to Nokia, a strategic engineering partner,
comprised approximately 42% of total revenue in 2001. In the third quarter of
2001, we amended our development program agreement with Nokia to, among other
things, provide for Nokia's funding of the project up to a maximum of
approximately $58 million. Under the amendment, generally, Nokia is obligated to
pay for the work based on negotiated commercial rates and to reimburse certain
expenses, all up to a maximum of approximately $58 million. Nokia is obligated
to pay the maximum amount when billable amounts equal or exceed the maximum
amount and we effect certain deliverables to Nokia. We are obligated to complete
the scope of work at our own expense to the extent that billable amounts exceed
the maximum. Previous to the amendment, revenue had been reported on a time and
materials basis and we had billed Nokia approximately $46 million under the
contract leaving approximately $12 million of revenue to be recognized. After
the amendment, we recognize revenue under the contract on a percentage of
completion basis. Of the $12 million remaining under the contract after the
amendment, approximately $6.2 million was recognized in 2001, and we expect to
recognize a substantial portion of the balance of $5.8 million in 2002. The
Nokia development project ends when the contractual scope of work has been
completed, which we currently expect to occur in 2003. Certain royalty-free
licenses granted under the contract continue after the development work has been
completed. We have not, at this time, entered into any arrangements with Nokia
to extend the work covered by this development project and there should be no
expectation that we will do so in the future. Although our costs associated with
the development effort have exceeded the maximum funding committed by Nokia, we
are continuing the development effort needed to complete our contractual
commitments on a self-funded basis. This could adversely affect both our cash
flow and our ability to achieve acceptable levels of profitability, especially
if such costs are greater than currently anticipated. Although cash receipts
from Nokia attributable to the development project were used to fund the
development work, other cash and cash equivalents on hand are enabling us to
complete the project and redirect certain of our resources to self-funded
development work. In addition, we have continued to explore potential strategic
relationships with third parties involving development and/or productization of
3G wireless technologies. As the Nokia development project winds down, we intend
to continue our operations as a developer of wireless technology and a licensor
of intellectual property.

         Revenues attributable to Sharp, one of our patent licensees, comprised
approximately 30% of total revenue in 2001. Revenues through June 30, 2002 have
continued at approximately the same rate. Our TDMA patent license agreement with
Sharp is royalty-bearing, non-exclusive, and generally non-transferable. It
covers Sharp's sale of PDC and PHS products on a world-wide basis through mid
2003, at which time it expires unless extended. Although we intend to seek to
extend the term of this license with Sharp, there can be no assurance that we
will be successful, either at all or on favorable or comparable terms. Since
this license is non-exclusive, we are not restricted from licensing the same
patents to multiple licensees and potential licensees. In addition, the
enforceability of our other license agreements would not be affected in the
event of a termination of the Sharp TDMA patent license. Expenditures relating
to this patent license have been minimal, being predominantly administrative in
nature. Further, cash receipts attributable to our TDMA patent license with
Sharp have been used for general corporate purposes, as opposed to any
particular program, expense or initiative. However, if we are not able to secure
sufficient cash flow or revenues from alternative sources and, at the same time,
maintain or increase current company expenditure levels, the inability to extend
this patent license could materially adversely affect both our cash flow and our
ability to achieve or sustain acceptable levels of profitability for the years
beyond 2003.



                                      -9-


         The Company is also a party to an additional patent license agreement
with Sharp covering Sharp's sale of GSM, N-CDMA and 3G Products on a world-wide
basis. This patent license agreement is royalty-bearing, non-exclusive,
generally non-transferable and expires upon the last to expire of the patents
licensed under the agreement. No revenues were generated under this patent
license agreement through the end of 2001. Revenues through June 30, 2002
associated with this patent license agreement were minimal. Since this license
is non-exclusive, we are able to license the same patents to multiple licensees
and potential licensees. Cash receipts attributable to this patent license
agreement with Sharp have been used for general corporate purposes, as opposed
to any particular program, expense or initiative. Expenditures relating to this
patent license have been minimal, being predominantly administrative in nature.

We Rely and Intend to Rely on Relationships with Third Parties.

         The successful execution of our strategic plan is partially dependent
on the establishment and success of relationships with equipment producers and
other industry participants. Our plan contemplates that these third parties will
give us access to product capability, markets and additional libraries of
technology. We currently have a limited number of such third party
relationships. To date we have not entered into any semi-conductor partnership
relating to our TDD technology. We have only one semi-conductor partner in our
FDD technology development effort, Infineon, and if we commence a FDD Access
Stratum development effort with another semiconductor company for terminal unit
applications, Infineon may engage a third party for the development or
modification of a new FDD Access Stratum. Our failure to enter into such
additional relationships, either on acceptable terms or at all, or our failure
to successfully execute such relationships, could impair our ability to
introduce portions of our technology and resulting products. In addition, delays
in entering into such relationships could cause us to miss critical market
windows. Further, the failure to maintain existing relationships and to
establish new relationships, all on satisfactory terms with capable partners,
could also adversely affect our future operating results.

         Our ability to derive revenues from our FDD development project is
currently largely dependent on Infineon's success in developing the integrated
circuits that incorporate the Joint 3G Protocol Stack, and on Infineon's and our
success in marketing and selling the Joint 3G Protocol Stack independently. We
may independently market and use our own portions of the Joint 3G Protocol Stack
being jointly developed with Infineon. Other anticipated benefits of the
Infineon relationship may be impacted by economic conditions affecting
semi-conductor companies in general and their ability to compete effectively,
Infineon's financial condition and engineering resources, and the market timing
and technological success of the Infineon platform upon which our designs are
based.

                                      -10-


         From time to time, certain companies may also assert that their patent,
copyright and other intellectual property rights are also important to the
industry or to us. In that regard, from time to time third parties provide us
with copies of their patents relating to digital wireless technologies and offer
licenses to such technologies. We in turn evaluate such patents and the
advisability of obtaining such licenses. If any of our products were found to
infringe on protected technology, we could be required to redesign such
products, license such technology, and/or pay damages to the infringed party. If
we are unable to license protected technology used in our products and/or if we
cannot economically redesign such products, we could be prohibited from
marketing such products. In such case, our prospects for realizing future income
could be adversely affected.

Our Revenue in the Short and Long Term Depends Upon Our Success in Enforcing
Patent Rights and Protecting Other Intellectual Property

         Our strategic plan depends, over the next several years, upon our
continued ability to generate patent licensing revenue related to the sale by
third parties of handsets and infrastructure compliant with the TDMA digital
cellular standards in use today among them GSM, IS-54/136, PDC and PHS. Our
ability to collect such revenue is subject to a number of risks. First, major
telecommunications equipment manufacturers have challenged, and we expect will
continue to challenge, the validity of ITC's patents. In some instances, certain
of ITC's patent claims have been declared invalid or substantially narrowed.
While ITC continues to maintain a worldwide portfolio of patents that it
believes are valid and infringed, and while we intend to vigorously defend and
enforce such patents, we cannot assure that the validity of our patents will be
maintained or that any of our key patents will be determined to be applicable to
any 2G or 3G product. Any significant adverse finding as to the validity or
scope of ITC's key patents could result in the loss of patent licensing revenue
from existing licensees and could substantially impair our ability to secure new
patent licensing arrangements. Additionally, while we license a portfolio of
patents, our 2G licensing revenues are expected to be impacted negatively over
time by the decline of the 2G market coupled with the expiration of certain of
our TDMA patents in the coming years.

         In the long term, our strategic plan depends upon our ability to
generate patent licensing revenue from the sale by third parties of 3G Products.
Our ability to generate such revenue is subject to certain risks. First, many of
the inventions which we believe will be employed in 3G Products are the subject
of patent applications which have not yet been issued by the relevant patent
reviewing authorities. While we intend to vigorously defend such patents, we
cannot assure that these patent applications will be granted or that the
resulting patents will be infringed by 3G Products. Second, we expect that the
validity of our patents will be challenged, and that we will be required to
enforce our patents against parties that refuse to take a license under our
patents. While we intend to vigorously defend and enforce our patents, we cannot
assure that the validity of our patents will be maintained or that any of our
patents will be determined to be applicable to any 3G Product. Finally, our
ability to generate 3G patent licensing revenue is dependent on our licensees'
success in selling 3G Products. This, in turn, may be affected by many other
factors, which are described in this "Risk Factors" section, including global
economic conditions, buying patterns of end users, competition and the changing
technology and market landscapes.

                                      -11-


         In addition, the cost of defending our intellectual property has been
and may continue to be significant. Litigation may be required to enforce our
intellectual property rights, protect our trade secrets, enforce confidentiality
agreements, or determine the validity and scope of proprietary rights of others.
As a result of any such litigation, we could lose our proprietary rights and/or
incur substantial unexpected operating costs. Any action we take to protect our
intellectual property rights could be costly and could absorb significant
management time and attention which, in turn, could negatively impact our
results of operations. Moreover, third parties could circumvent the patents held
by our wholly-owned subsidiary, ITC, through design changes. Any of these events
could adversely affect our prospects for realizing future income.

         Together with ITC, we are currently engaged in a significant patent
infringement litigation with Ericsson, Inc. (Ericsson) over certain of ITC's
patents. During the course of this litigation (or a future yet unidentified and
unfiled litigation, should such litigation arise), certain of ITC's key patents
could be found to be invalid or not infringed or its patent claims could be
narrowed. Any such adverse finding as to the validity or scope of ITC's key
patents could result in the loss of patent licensing revenue from existing
licensees and could substantially impair our ability to secure new patent
licensing arrangements.

Our License Agreements Contain Provisions which Could Impair Our Ability to
Realize Licensing Revenues

         Certain of our licenses contain provisions which could cause the
licensee's obligation to pay royalties to us to be reduced, terminated or
suspended for an indefinite period, with or without the accrual of the royalty
obligation. In addition, certain of our licensees had, in the past, stated,
among other things, that the outcome of a prior litigation over ITC's patents
materially impacted the royalties due under their license agreements and have
refused to pay royalties under their license agreements. While we believe that
these positions have been meritless, similar positions could be asserted in the
event that a licensee's obligation to pay royalties to us in the future is
either terminated or indefinitely suspended, or in the event that ITC's patents
are held invalid or unenforceable, and these positions could be found to have
merit. The assertion or validity of such positions could interfere with ITC's
ability to secure new licenses or to generate recurring licensing revenue under
the existing agreements.

We Face Risks From Doing Business in Global Markets

         A significant part of our strategy involves our continued pursuit of
growth opportunities in a number of international markets. In doing so, we are
subject to the effects of a variety of uncontrollable and changing factors,
including: difficulty in protecting our intellectual property in foreign
jurisdictions; inability to enter foreign markets; government regulations,
tariffs and other applicable trade barriers; currency control regulations;
social, economic and political instability; natural disasters, acts of terrorism
and war; potentially adverse tax consequences; inability to enforce contractual
commitments abroad; and general delays in remittance and difficulties of
collecting non-U.S. payments. In addition, we are also subject to risks specific
to the individual countries in which our customers, our licensees and we do
business.

                                      -12-


         A long lasting downturn in the global economy that impacts the wireless
communications industry could negatively affect our revenues and operating
results. The global economy is in a slowdown that has had wide-ranging effects
on our licensees and the markets that we target, particularly wireless equipment
manufacturers and network operators. In particular, recent economic weakness in
Japan, from which a significant portion of our 2001 revenue was derived, may
continue to lead to decreased sales by current and prospective licensees. This
downturn has had and is expected to continue to have a negative effect on, among
other things, the ability and willingness of companies to invest in
technological and product development, and the sales of our licensees (which, in
turn, affects our revenues). We cannot predict the depth or duration of this
downturn, and if it grows more severe or continues for a long period of time,
our ability to increase or maintain our revenues and other operating results may
be impaired.

Consolidations in the Wireless Communications Industry Could Adversely Affect
Our Business

         The wireless communications industry has experienced consolidation of
participants, and this trend may continue. ITC's licensing opportunities are
affected by the increasing concentration of the wireless industry, particularly
as to infrastructure, which results in a substantial portion of the licensing
opportunities being concentrated in a small number of non-licensed
manufacturers, many of whom are opposing the validity of ITC's patents in
multiple forums. In addition, certain business combinations may result in the
loss or diminution of existing royalty obligations. Further, if wireless
carriers consolidate with companies that utilize technologies competitive to our
technologies, we may lose market opportunities.

We Depend on Sufficient Engineering Resources

         Competition for qualified and talented individuals with engineering
experience in emerging technologies, like WCDMA, is intense. There can be no
assurance that we will be able to attract and retain a satisfactory number of
such individuals. The failure to attract and retain highly qualified personnel
could interfere with our ability to undertake additional technology and product
development efforts as well as our ability to meet our strategic objectives.

Market Predictions are Forward-Looking in Nature

         Our market strategy is based on our own predictions and on analyst,
industry observer and expert predictions, which are forward-looking in nature
and are inherently subject to risks and uncertainties. The validity of their and
our assumptions, the timing and scope of the 3G market, economic conditions,
customer buying patterns, timeliness of equipment development, pricing of 3G
Products, growth in wireless telecommunications services that would be delivered
on 3G devices, and availability of capital for infrastructure improvements could
affect these predictions. If any of these predictions are wrong, our strategic
plan may require a significant shift and our operating results could be
adversely affected.

We Face Risks from Terrorist, Cyber and Other Attacks

         None of our properties or data were damaged or compromised as a result
of the terrorist attacks that occurred in the United States on September 11,
2001. Our operations during the period that followed suffered only minor
disruption such as delayed travel. However, we could be impacted, in the future,
by a terrorist, cyber or other attack either directly or indirectly through our
customers or vendors.

                                      -13-


If Wireless Handsets Pose Health and Safety Risks, Demand for Our Products in
Development and Those of Our Licensees and Customers Could Decrease

         Media reports and certain studies have suggested that radio frequency
emissions from wireless handsets may be linked to health concerns, such as brain
tumors, other malignancies and genetic damage to blood, and may interfere with
electronic medical devices, like pacemakers, telemetry and delicate medical
equipment. If concerns over radio frequency emissions grow, this could
discourage the use of wireless handsets, and cause a decrease in demand for our
products and those of our licensees and customers. There are also some safety
risks associated with the use of wireless handsets while driving. Concerns over
these safety risks and the effect of any legislation that may be adopted in
response to these risks could reduce demand for our products in development and
those of our licensees and customers.

Our Stock Price is Volatile

         Historically, market prices for securities of companies involved in the
wireless telecommunications industry have been volatile. In addition, market
prices for the Common Stock have historically been particularly volatile due, in
part, to the Company's history of quarterly fluctuations of revenues and
operating results. Announcements of, among other things, technological
innovations or new commercial products by the Company or its competitors,
developments concerning proprietary technologies, results of patent enforcement
activities, regulatory developments in both the United States and other
countries, and global and national economic and political factors, as well as
period-to-period fluctuations in financial results, may have a significant
impact on the market price of the Common Stock.

                              PLAN OF DISTRIBUTION

         The Company is registering the Shares on behalf of the Selling
Shareholders. As used herein, "Selling Shareholders" includes donees, pledgees,
transferees or other successors-in-interest selling shares received from the
named Selling Shareholders as a gift, pledge, partnership distribution or other
non-sale related transfer, after the date of this Prospectus. All costs,
expenses and fees in connection with the registration of the Shares offered
hereby will be borne by the Company. Brokerage commissions and similar selling
expenses, if any, attributable to the sale of Shares will be borne by the
Selling Shareholders. Sales of Shares may be effected by Selling Shareholders
from time to time in one or more types of transactions (which may include block
transactions) on the Nasdaq National Market, in negotiated transactions, through
put or call options transactions relating to the Shares, through short sales of
Shares, or a combination of such methods of sale, at market prices prevailing at
the time of sale, or at negotiated prices. Such transactions may or may not
involve brokers or dealers. The Selling Shareholders have advised the Company
that they have not entered into any agreements, understandings or arrangements
with any underwriters or broker-dealers regarding the sale of their securities,
nor is there an underwriter or coordinating broker acting in connection with the
proposed sale of Shares by the Selling Shareholders.

         The Selling Shareholders may effect such transactions by selling Shares
directly to purchasers or to or through broker-dealers, which may act as agents
or principals. Such brokers-dealers may receive compensation in the form of
discounts, concessions, or commissions from the Selling Shareholders and/or the
purchasers of Shares for whom such broker-dealers may act as agents or to whom
they sell as principal, or both (which compensation as to a particular
broker-dealer might be in excess of customary commissions).

         The Selling Shareholders and any broker-dealers that act in connection
with the sale of Shares might be deemed to be "underwriters" within the meaning
of Section 2(11) of the Securities Act, and any commissions received by such
broker-dealers and any profit on the resale of Shares sold by them while acting
as principals might be deemed to be underwriting discounts or commissions under
the Securities Act. The Company has agreed to indemnify the Selling Shareholders
against certain liabilities, including liabilities arising under the Securities
Act. The Selling Shareholders may agree to indemnify any agent, dealer or
broker-dealer that participates in transactions involving sales of the Shares
against certain liabilities, including liabilities arising under the Securities
Act.

         Because the Selling Shareholders may be deemed to be "underwriters"
within the meaning of Section 2(11) of the Securities Act, the Selling
Shareholders will be subject to the prospectus delivery requirements of the
Securities Act. The Company has informed the Selling Shareholders that the
anti-manipulative provisions of Regulation M promulgated under the Exchange Act
may apply to their sales in the market.

         The Selling Shareholders also may resell all or a portion of the Shares
in open market transactions in reliance upon Rule 144 under the Securities Act,
provided they meet the criteria and conform to the requirements of such Rule
144.

                                      -20-


         Upon the Company being notified by any of the Selling Shareholders that
any material arrangement has been entered into with a broker-dealer for the sale
of Shares through a block trade, special offering, exchange distribution or
secondary distribution or a purchase by a broker or dealer, a supplement to this
prospectus will be filed, if required, pursuant to Rule 424(b) under the
Securities Act, disclosing (i) the name of each such Selling Shareholder and of
the participating broker-dealer(s), (ii) the number of shares involved, (iii)
the price at which such Shares were sold, (iv) the commissions paid or discounts
or concessions allowed to such broker-dealer(s), where applicable, (v) that such
broker-dealer(s) did not conduct any investigation to verify the information set
out or incorporated by reference in this prospectus and (vi) other facts
material to the transaction. In addition, upon the Company being notified by any
of the Selling Shareholders that a donee, pledgee, transferee or other
successor-in-interest intends to sell more than 500 shares, a supplement to this
Prospectus will be filed.

                                  LEGAL MATTERS

         The validity of the Common Stock registered hereunder has been passed
upon for the Company by Lawrence F. Shay, Esq., 781 Third Avenue, King of
Prussia, Pennsylvania 19406. Mr. Shay is General Counsel, Vice President and
Corporate Secretary of the Company, and Mr. Shay owns 1,421 shares of Common
Stock and options to purchase 50,000 shares of Common Stock.

                                     EXPERTS

         We have not been able to obtain, after reasonable efforts, the written
consent of Arthur Andersen to our naming it in this Prospectus as having
certified our consolidated financial statements for the three years ended
December 31, 2001, as required by Section 7 of the Securities Act. Accordingly,
Arthur Andersen will not have any liability under Section 11 of the Securities
Act for false and misleading statements and omissions contained in this
prospectus, including the financial statements, and any claims against Arthur
Andersen related to any such false and misleading statements and omissions may
be limited.

Item 15. Indemnification of Directors and Officers

         Sections 1741-1750 of the Pennsylvania Business Corporation Law of 1988
(the "BCL") and the Company's By-Laws, as amended through March 21, 2002,
provide for indemnification of the Company's directors and officers and certain
other persons. Under Sections 1741-1750 of the BCL, directors and officers of
the Company may be indemnified by the Company against all expenses incurred in
connection with actions (including, under certain circumstances, derivative
actions) brought against such director or officer by reason of his or her status
as a representative of the Company, or by reason of the fact that such director
or officer serves or served as a representative of another entity at the
Company's request, so long as the director or officer acted in good faith and in
a manner he or she reasonably believed to be in, or not opposed to, the best
interests of the Company. As permitted under the BCL, the Company's By-Laws
provide that the Company (to the full extent permitted under the BCL) shall
indemnify directors and officers against all expenses incurred in connection
with actions (including derivative actions) brought against such director or
officer by reason of the fact that he or she is or was a director or officer of
the Company, or by reason of the fact that such director or officer serves or
served as an employee or agent of any entity at the Company's request, unless
the act or failure to act on the part of the director or officer giving rise to
the claim for indemnification is determined by a court in a final, binding
adjudication to have constituted willful misconduct or recklessness. The
Company's By-Laws authorize the Company to purchase and maintain insurance to
insure its indemnification obligations on behalf of any person who is or was or
has agreed to become a director, officer, employee or agent of the Company, or
is or was serving at the request of the Company as a director, officer, employee
or agent of another corporation, partnership, joint venture, trust or other
enterprise, against any expense, liability or loss asserted against him and
incurred by him or on his behalf in any such capacity.

Item 17. Undertakings.

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Company pursuant to the provisions discussed in Item 15 of this Registration
Statement, or otherwise, the Company has been advised that in the opinion of the
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the Company
of expenses incurred or paid by a director, officer or controlling person of the
Company in the successful defense of any action, suit or proceeding) is asserted
by such director, officer or controlling person with the securities being
registered, the Company will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

         The undersigned Registrant hereby undertakes: (1) to file, during any
period in which offers or sales are being made, a post-effective amendment to
this Registration Statement: (i) to include any prospectus required by Section
10(a)(3) of the Securities Act; (ii) to reflect in the prospectus any facts or
events arising after the effective date of this Registration Statement (or the
most recent post-effective amendment thereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth in the
registration statement (notwithstanding the foregoing, any increase or decrease
in volume of securities offered (if the total dollar value of securities offered
would not exceed that which was registered) and any deviation from the low or
high and of the estimated maximum offering range may be reflected in the form of
prospectus filed with the Commission pursuant to Rule 424(b) if, in the
aggregate, the changes in volume and price represent no more than 20 percent
change in the maximum aggregate offering price set forth in the "Calculation of
Registration Fee" table in the effective registration statement); and (iii) to
include any material information with respect to the plan of distribution not
previously disclosed in the registration statement or any material change to
such information in the registration statement; provided, however, that clauses
(i) and (ii) above do not apply if the information required to be included in a
post-effective amendment by those clauses is contained in periodic reports filed
by the Company pursuant to Section 13 or Section 15(d) of the Exchange Act that
are incorporated by reference in this Registration Statement; (2) that, for the
purpose of determining any liability under the Securities Act, each such
post-effective amendment shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof; and
(3) to remove from registration by means of a post-effective amendment any of
the securities being registered which remain unsold at the termination of the
offering.


                                      II-2



         The Company hereby undertakes that, for purposes of determining any
liability under the Securities Act, each filing of the Company's annual report
pursuant to Section 13(a) or Section 15(d) of the Exchange Act that is
incorporated by reference in this Registration Statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

the Company certifies that it has reasonable grounds to believe that it meets
all of the requirements for filing on Form S-3 and has duly caused this
Amendment No. 2 to Registration Statement to be signed on its behalf by the
undersigned, thereunto duly authorized, in King of Prussia, Pennsylvania, on
November 13, 2002.
